Random Seed:
(integer; 1 - 2147483561)
This is the random seed that will be passed to the ray
generator. This allows the generator to create a thoroughly
random and statistically appropriate sampling of rays.
If you're trying to recreate a previous sampling, please
enter the seed that was used for that run. This seed
will be stored in the header of the generated data files
for future reference.
Coordinate System:
- Theta & Phi:
-
- Theta
-
(arcminutes; 0 - 120)
A single number specifying theta.
Please note that, for values less than 1 arcminute,
dmcoords returns a value in arcseconds. This
needs to be converted to arcminutes.
- Phi
-
(degrees; 0 - 360)
A single number specifying phi.
Spectral/Limit Specification:
Spectral specification of the PSF to be simulated.
Possible Specifications:
- Energy & Density
-
- Energy
-
(keV; 0.2 - 10)
Up to 10 numbers, seperated by spaces, specifying the
energies for which you wish to simulate. Each
energy is simulated separately. Note: you
may ignore the `Browse' button.
- Density
-
(rays/mm2; 0.0001 - 10)
This determines the density of rays that will be
generated at the entrance aperture. The number of rays
that arrive at the focal plane are determined by the
HRMA effective area at the input energies. This option
is useful when assembling a composite spectrum from
mono-energetic simulations.
- Spectrum & Exposure Time
-
- Spectrum
-
(ascii file)
Description: This is a file (on your computer) that
will be uploaded to our servers. This file must contain a
definition of the spectrum at the entrance aperture of the
HRMA for which you would like a PSF to be simulated.
The easiest way to create this file is to follow the
instructions given in the
Preparing to Run ChaRT
thread, which explain how to use the
chart_spectrum.sl script to produce a
spectrum with the correct units.
Format: This is a simple ASCII file consisting of
two columns separated by spaces or tabs. The first column
is the energy (in keV) at the center of the bin and other
column is the flux (in photons/cm2/sec) of the
bin.
- Exposure Time
-
(ksec; 0 - 100)
This determines for how long the simulation will
run. This requires an input spectrum with an absolute
flux at each energy.
